Abstract

Enterohemorrhagic Escherichia coli (EHEC) are a pathogenic subgroup of Shiga toxin-producing E. coli (STEC), and have demonstrated ability to cause severe intestinal disease and the hemolytic uremic syndrome (HUS). Cattle are the major reservoir of EHEC, where the bacteria can persist asymptomatically for years. Of particular concern are a small percentage of animals in herds that shed extremely high numbers of EHEC, termed ‘supershedders’, and are responsible for the majority of EHEC spread and contamination. Another transmission route is through the environment where EHEC can survive for weeks to many months, remaining viable in bovine feces, soil and water. EHEC contamination of meat during slaughter or processing, or contamination of plants via EHEC-containing water or manure are major routes of entry into the food chain. Several hundred outbreaks caused by EHEC O157 as well as non-O157 strains have been identified in industrialized countries worldwide. Current and future research efforts are focused on rapid outbreak identification, development of therapeutics, and implementation of preventative measures.
